The flash memory is erased by the chip erase (erasing an entire flash area) or sector erase (erasing sectors in
4-kbyte units). The erased area is filled with FFH. When the read protection is enabled, the sector erase in
the flash erasing mode can not be performed. To disable the read protection, perform the chip erase. Before
erasing the flash memory, TMP86F409NG checks the passwords except a blank product. If the password is
not matched, the flash memory erasing mode is not activated.
Data is written to the specified flash memory address for each byte unit. The external controller must trans-
mit the write data in the Intel Hex format (Binary). If no error is encountered till the end record,
TMP86F409NG calculates the checksum for the entire flash memory area (F000H to FFFFH), and returns
the obtained result to the external controller. When the read protection is enabled, the flash memory writing
mode is not activated. In this case, perform the chip erase command beforehand in the flash memory eras-
ing mode. Before activating the flash memory writing mode, TMP86F409NG checks the password except a
blank product. If the password is not matched, flash memory writing mode is not activated.
The RAM loader transfers the data in Intel Hex format sent from the external controller to the internal
RAM. When the transfer is completed normally, the RAM loader calculates the checksum. After transmit-
ting the results, the RAM loader jumps to the RAM address specified with the first data record in order to
execute the user program. When the read protection is enabled, the RAM loader mode is not activated. In
this case, perform the chip erase beforehand in the flash memory erasing mode. Before activating the RAM
loader mode, TMP86F409NG checks the password except a blank product. If the password is not matched,
flash RAM loader mode is not activated.
The checksum is calculated for the entire flash memory area (F000H to FFFFH), and the result is returned
to the external controller. Since the BOOTROM does not support the operation command to read the flash
memory, use this checksum to identify programs when managing revisions of application programs.
The code used to identify the product is output. The code to be output consists of 13-byte data, which
includes the information indicating the area of the ROM incorporated in the product. The external control-
ler reads this code, and recognizes the product to write.
(In the case of TMP86F409NG, the addresses from F000H to FFFFH become the ROM area.)

Erases the flash memory area (address F000H to FFFFH).
Writes to the flash memory area (address F000H to FFFFH).
Writes to the specified RAM area (address 0050H to 023FH).
Outputs the 2-byte checksum upper byte and lower byte in this order for the
entire area of the flash memory (address F000H to FFFFH).
Outputs the product ID code (13-byte data).
Outputs the status code (7-byte data) such as the read protection condition.
Enables the read protection.
